Abstract-In this paper, supercontinuum generation in terahertz region in a silicon-based rib waveguide is simulated via solving the generalized nonlinear Schrödinger equation (GNLSE). First, a silicon waveguide with a zero-dispersion wavelength in the terahertz region is designed with the help of Lumerical software and then its linear and nonlinear parameters such as loss, nonlinear parameter and high-order dispersion are calculated. Finally, terahertz supercontinuum spectrum, with the help of MATLAB software via the split-step Fourier (SSF) method is simulated and the effects of different parameters such as input pulse power, pulse width and length of waveguide are investigated.
